JOHN L. DUVAL, OF HOUSTON, TEXAS.

BALE-BAND TIGHTENER.

SPECIFICATION forming part of Letters PatentNo. 591,333, dated October 5, 1897.-

Application filed October 1, 1896. Serial No. 607,526. (No model.)

To all whom, it may concern:

Be it known that I, JOHN L. DUVAL, of Houston, in the county of Harris and State of Texas, have invented a new and Improved. Bale-Band Tightener, of which the following is a full, clear, and exact description.

The invention relates to baling-presses; and its object is to provide a new and improved bale-band tightener which is simple and durable in construction and arranged to permit the operator to conveniently place the bands in position and fasten the ends together after the bale is pressed.

The invention consists of platens, each provided with grooves or recesses for the bands, and spring-pressed bars extending between the grooves or recesses and beyond the face of the platen and serving'as guides for the bands and a support for the bale before it'is compressed, the bars being adapted to recede into recesses formed in the platen when pressure is brought to bear upon the same.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse section of the improvement. Fig. 2 is an end elevation of the same with the guide-bars in areceding position. Fig. 3 is a similar View of part of the same with the guide-bars in a different position. Fig. 4 is a-sectional side elevation of the improvement, showing the ends of the bands overlapping for receiving the fastener; and Fig. 5 is a sectional side elevation of the bale-band-fastening device.

On the opposite faces of the lower andupper platens A A are formed transversely-extending recesses or grooves A A respectively, adapted to receive the bands B B for tightening the bale after the same is pressed between the platens in the usual manner. The

bands B B, arranged opposite each other,

have their ends overlapping when the bale isv Figs. 2 and 5 and more fully described hereinafter.)

The bale-bands B B are arranged between bars D D, respectively, fitted to slide in recesses A A respectively, formed in the platens A A, next to the band-receiving recesses A A The bars D D extend normally beyond the inner faces of the platens, as illustrated in Figs. 1 and 3, so that the bands lie between adjacent bars, each of which extends throughout the length of the platen, as indicated in Fig. 1. The bars D D thus act as guides for the bands when they are passed between the platens and into the grooves or recesses A A The outer ends of the guidebars D D are provided with guide-rods D D respectively, fitted to slide in brackets on the platens-and pressed on by springs E E, respectively, so as to hold the said guide-bars normally in an innermost position, as shown in Fig. 3. Now it will be seen that when the press is in use and the material is between the platens and pressed by the same in the usual manner then the bars D D will be forced back into their recesses A A until the faces of the bars are flush with the faces of the platens, as'indicated in Fig. 2, and the material is formed into the bale withthe bands B B extending over the top and bottom of the bale and with the ends projecting beyond the ends of the bale, as indicated in Fig. 1. The band ends are then bent downwardly, so as to overlap, as indicated in Fig. 4E, and then a suitable tool is employed for forming a loop 13 on the overlapping ends, as is plainly shown in Fig. 5, and this loop is engaged by a link C and a key 0 for fastening the ends of the band together, as indicated in Figs. 2 and 5. When the platens recede to permit of removing the bale, then the guiding-bars D D again move into their outermost position (shown in Figs. 1 and 3) and the operation is then repeated for a second bale. It will be seen that the grooves A A form fixed guides for the bands to rest on after they are passed between the platens, being guided between the bars D D, the grooves for the bands being of a depth corresponding to the thickness of the band. The grooves in the bars D D serve to allow the escape of air from the top and bottom of the bale in compressing. The ends of the bars D D are ehainfered, as shown in Fig. 1, to relieve the bar froin strain during the compression and to facilitate picking up of the band for tightening the ends thereof, as explained. It is expressly understood that the platens or jaws on closing carry the bands along and force the same into the top and bottom of the bale at the nearest points, so that the bale can be properly tied by the bands.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 7 A baling-press provided with platens formed with transverse groo'ves for-the reception of the bands and of a width and depth corresponding to the width and thickness of said bands, and recesses between pairs of grooves considerably deeper than the same, bars having their inner faces slightly rounded and formed with longitudinal grooves to allow air to escape from the top and bottom of the bale in compressing, the bars being fitted to slide in said recesses and having their inner ends chamt'ered and their-outer ends provided with guide-rods, brackets along the side edges of the platens and receiving said guide-rods to slide therein, and springs encircling said rods and forcing said bars normally out of re cesses in which they are fitted and beyond the faces of the platens, the said bars receding into their recesses which are of such a depth that the bars will be flush with the faces of the platens when the bale is compressed, as and for the purpose set forth.
